Once upon a time, Saul (desired) who was born in Tarsus went to live in Israel. He was trained to be a hardliner, who would defend Jewish religion at any cost.
In the early ministry of Jesus’ disciples in Jerusalem, Saul unconsciously became anti-Christ. He persecuted those who believed on Jesus.
Saul decided to go to Damascus (Syria) to persecute disciples of Jesus. On the way to Damascus Jesus revealed himself to Saul, Saul fell on the earth.
Saul was led to Damascus – for the Splendor of Christ blinded him. Jesus used Hananiah to baptize and give his sight back.
Saul humbled himself before God, testified the death and Resurrection of Jesus for forgiveness of sins to everyone without favor (Jews, Greeks or Gentiles). In the years to follow, Saul was persecuted for his firm faith on Lord Jesus Christ.
Saul ministered in Asia minor, Greece and Rome. He wrote many powerfull books in the New Testament. He spoke fluent Greek and Hebrew. Eventually he was called Paul (small/little).
Paul was beheaded by Nero (67 A.D.) in Rome. It is said Paul’s pupils erected a memorial for him. This memorial eventually became a church (St Paul Outside The Walls) for it is outside the Aurelian walls.
St Paul complex is one of the four main basilicas in Rome: St John Lateran, St Maria Maggiore and St Peter. Paul’s tomb is believed to be right below the altar in the church.
